`Specification of Letters Patent,

To all whom it may cof/wem: Be it known that I, JEssE L. HOLMES, a citizen of the United States of America, residing at Juno, in the county of Henderson and State of .l`ennessee;.l1ave -invented certain new and useful Improvementsv *in GroundsTilling Machinesofwhich the following' is a specication. This invention relates to a ground tilling machine, and more particularlyto a device A vadapted'to plow and tho-roughly pulverize the groundeat a single operation.. y g Y To accomplish this the machine comprisesv a plurality oicutting elements, said cutting elements first slicing the ground or sod intov a] plurality :of longitudinal vstrips. in such manner that whenv the plow turns these strips over they 4are `thoroughly broken upy and pulverized and ready for seeding with- 26 out any further operation. The slicing disks in this invention. are `luti1ized to partially support the weight of the machine, andthe driver, and to that end they perform a doublefunction, and vsince- 25- they cut into the ground they resist any side 'draft to such `an'extent that the extra draft brought upon-the team bythe simultaneous action ofthe disks-and the plow 'is largely compensated for.

I 30 lFurther objects and advantages-of .the invention will be set'. forth in the detailed seripti'on which now follows.

In` the accompany-ing drawing Figure 1 is a side elevation of a machine constructed 135 inaccordance with theinve'ntion.- Fig'. 2 is l r arear elevation thereof. .F ig. 3 is a detailed sectional view upon line'A.-%A.of Fig. 2.

through bars 17 and clevis bar 18.

' 46 whichv carries the drivers seat 47. The

rear' end of thefframe member 42 is bifurcated for the reception of the end 48 of frame member 49, said frame member being pivoted upon a pin 50. Passing through the rear ends of the frame members 39 and 49l is a bolt 51. This boltV passes through bars 452, said bars beingspaced apart by a spacing block 53 whieh,is maintained in position by a bolt 54,-ar1d it is between 'the bars 52 that crank arm 33 is pivoted, as' hereinv before set forth. One of the boltsl 14 also secures in position an eye 55, with which' ak bar 56 has hinged engagement through the Ymedium of an eye 57. Bar 56 has secured thereto,` a bar 58 by. means of a rivet or other .fastening indicated at 59 (see F ig. 7).

' Upstanding posts 60 carried by theframe member 5 pass through the bar 5S and have nuts 61 threaded upon their upper ends.

Springs 62 bear between these nuts and the bar 58 and normally tend to resist upward movement of said bar. Through the outer end of the bar 56 passes a post 63 and upon the upper-end of this post is threaded a nut or other head member 64. The lower v y 'end of this post is secured at 65 to a bar 6G that is secured to and ,moves with beam 39. It will therefore be seen that the beam 39 which 'as hereinafter set fortlnlcarries the disk plow, is capable of a vertical movement with relation to the frame member' said movement being resisted by the action .of the springs, whereby thedisks 12 are not forced out of tlie ground when the plow rides over'an obstruction, and in like manner the plow is not forced out of the ground hen the disksy ride over an obstruction. The bar 66 (see Figs. 5 and 7) has secured thereto by a bolt and slot connection 68 a depending hanger bar 69, and the inner face.

' of this hanger bar is rounded at 70 to permit the necessary movement of said hanger with relation to bar 66 when the hanger bar is swung yforward or rearwardly to change the angle of the plow. lThe plow employed and supported by beam 39 may be either a isk plow or a mold bo-ard plow, and both forms have been illustrated. When a disk plow is employed, the disk which may be either serrated or plain, and which is indicatedat 71y is supported from a hub which comprises (see Fig. 6) a tapered inner sleeve 72v which entersa tapered outer sleeve 73..'

Ay bolt 74 passes through a washer 75,

through the disk and through said sleeves,

and is secured to the hanger bar 69 by a nut 76. The inner sleeve '72 carries a flange '77 having fingers 78 which enter openings 79 formed in the disk to cause the disk to turn with the inner sleeve. The inner end of the outer sleeve is, therefore, supported from the hanger bar 69,`but the outer por# tion thereof is supported by a yielding loop member 80, the bight of which is given a single turn about the sleevel and the terminal ends of which are secured by bolts prising spaced bars 87 having slotted upper ends 88 through which a bolt 89 passes to secure said plow to the offset portion 40 of beam 39, as will be readily understood.

This permits the adjustment of the plow to any desired angle.

While I have shown rotative disks 12, it

is to be understood that the invention is not limited to having these disks rotate. They might` be fixed knives like the runners of a sled, and they would operate in that oase to slice the sod or earth in the same manner that the4 disks slice it. Since the plow does not cut as wide a furrow as the path traversed by the disks 12, it follows that these disks, dur-ingtheir successive passages, overlap their track and consequently thev earth is cutinto narrow strips and when turned out by the plow readily falls apart and leaves the ground suiiiciently pulverized for immediate seeding without the use of a harrow o-r roller: The invention further is not limited to the number of disks 12 which may be employed, or to themanner of mounting these disks. Any desired number of disks may be used and these disks may be set closer together or farther apart than is shown in the drawing, and they may be secured in various ways to the shaft. While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview, such .changes as may be made within 'the scope of the appended claims. l
